Physical education is taught to all Saint Gregory students. Students in grades first through eighth attend class for a half hour twice a week while kindergarteners attend class for fifty minutes twice a week. Students work in small groups to complete circuit activities that emphasize gross motor skills, fair play, and exercise while having fun at the same time. Students learn the skills needed to play specific games, while also learning the proper rules to follow. All classes follow the curriculum guidelines of the Archdiocese of San Francisco as well as the California State Content Standards for physical education.
